Salmonella Outbreaks in San Francisco: Local Response & Prevention

How SFDPH Tracks and Responds to Salmonella Outbreaks

The San Francisco Department of Public Health works in coordination with the CDC and California Department of Public Health (CDPH) to identify, investigate, and contain Salmonella outbreaks. When cluster cases are detected—typically through lab reports showing matched strains—SFDPH epidemiologists conduct traceback investigations to identify contaminated food sources and production facilities. Public health officials issue local health alerts, communicate with retailers and food businesses, and may request product recalls through the FDA. SFDPH publishes outbreak summaries on its official website and coordinates with the state to ensure swift response across Bay Area jurisdictions.

Salmonella Transmission Through Poultry, Eggs, and Produce

Salmonella colonizes the intestines of live poultry and can contaminate eggs during formation or through cross-contact with fecal material. Raw or undercooked chicken, turkey, and duck pose significant risk; eggs—even those with intact shells—may harbor Salmonella internally. Produce contamination typically occurs through irrigation water, soil contact, or handling by infected workers; leafy greens, tomatoes, and melons have been linked to past outbreaks. Cross-contamination in home kitchens amplifies risk when raw poultry juices contact ready-to-eat foods or surfaces. Proper cooking (165°F for poultry), handwashing, and separate cutting boards are essential barriers.
